src: fix ValidateDSAParameters when fips is enabled

Currently, the following compilation errors are generated when
configuring --openssl-is-fips:

../src/node_crypto.cc: In function ‘bool
node::crypto::ValidateDSAParameters(EVP_PKEY*)’:
../src/node_crypto.cc:4886:55: error: ‘pkey’ was not declared in this
scope
   if (FIPS_mode() && EVP_PKEY_DSA == EVP_PKEY_base_id(pkey.get())) {
                                                       ^~~~

   if (FIPS_mode() && EVP_PKEY_DSA == EVP_PKEY_base_id(pkey.get())) {

            (L == 3072 && N == 256)
                                   ^
                                   ;
   }

This commit fixes the errors, and after this compilation is successful.
